Answer:
139
Step-by-step explanation:
a pentagon has degrees that add up to 540 so considering youre given 401 degrees the remaining angle has to be 139
Answer:
3.24 feet.
Step-by-step explanation:
We have been given that length of time ( T ) in seconds it takes the pendulum of a clock to swing through one complete cycle is given by the formula , where, L is the length, in feet, of the pendulum.
To find the length of pendulum, we will substitute in the given formula as:
Divide both sides by 2:
Substitute :
Multiply both sides by :
Square both sides:
Switch sides:
Therefore, the length of the pendulum is approximately 3.24 feet.
First you find the percent of 12. 8% of 12 is 0.96. you must add that to 12 and you get $12.98
We just need to solve the equation in order to find the value.
So we subtract 5 from both sides of the euqation and get
Now we divide by 3 on both sides and get
So the answer is C.
Hope this helps!
